7.3 Optical resonators: stability and mode structure
3 min read•Last Updated on July 22, 2024
Optical resonators are the heart of lasers, confining and amplifying light using mirrors and a gain medium. They come in various configurations, each with unique properties that affect stability and performance.
Understanding resonator stability is crucial for laser design. ABCD matrices help analyze light propagation, while the stability criterion determines if light remains confined. Transverse modes and resonance frequencies further shape the output beam's characteristics.

Optical resonators confine and amplify light using two or more mirrors (flat or curved)
Common configurations: Fabry-Perot cavities and ring resonators
Gain medium amplifies light through stimulated emission placed between the mirrors
